Also I added another one a while back, sadly not updated very often. smhrazor is the tech-related blog of Charles Wright, for the Sydney Morning Herald/Melbourne Age. I might see if I can request it be changed to his personal blog.
Finally a couple of Triple J podcast feeds. jjjrawcomedyhl is the RSS feed for the highlights of Triple J's Raw Comedy competition finalists. Got updated sporadically, but there should still be a couple good ones. drkarl wasn't added by me, so I'm unsure if its been mentioned here before. If you've never heard of Dr Karl, he is well known by the Australian public as the man who knows everything. He hosts a one hour radio show every Thursday on Triple J, answering questions about stuff (usually scientific). This is the podcast.
